Show HN: Command Center, the AI coding env for people who care about quality Hi HN! We’re Jimmy and Ray. Jimmy is a Thiel Fellow with a Ph. D. from MIT who has worked on programming tools for 15 years; Ray became VP of Sales at a $2B company when he was 19 and has built side-businesses vibe-coding.<p>Last year, we set to answer the question “If AI can write code 100x faster, then why aren’t you shipping 100x faster?” What we learned shocked us — even fairly nontechnical people and solo founders told us they were spending more than half of their development time reading the AI-written code. And much of the rest of the time was spent either de-slop-ping it, or wishing they had done so.<p>As luck turns out, our last two products were a tool that quickly onboards people to large codebases ( <a href="https:&#x2F;&#x2F;x.com&#x2F;0xjimmyk&#x2F;status&#x2F;1873357324229984677" rel="nofollow">https:&#x2F;&#x2F;x.com&#x2F;0xjimmyk&#x2F;status&#x2F;1873357324229984677</a> ) and trainings that taught deep concepts of code quality to CEOs, YC founders, and engineers at top companies ( mirdin.com ), so we were extremely well-positioned to solve these problems.<p>Command Center is an agentic coding environment focused on quality. With a few keypresses, you can start building 3 features at once and soon have 3 diffs ready, each consisting of 2000 changed lines across 50 files….<p>This is normally the point where you think “Crap, what now?”<p>With Command Center, at this point you simply click “Refactor,” and watch the vibed slop turn into readable robustness. Then you click “Generate Walkthrough,” and then suddenly, to read a 2000 line diff, instead of scrolling up and down trying to make sense of it, you just press the right arrow key 200 times. See something you don’t like? Click on line 37, type “Do this and all other network fetches in the background Cmd+Enter,” and you have a few more agents getting your code into final shape. Click or type “Commit,” “Push,” “Create PR” — you just shipped a high quality, non-slop feature<p>We’re striving to be the best at every step of the pipeline, but can just try Command Center in pieces wherever you feel your current workflow is weakest. We have users who do all their coding in Zed or the Codex app, and then jump over to Command Center for a walkthrough when it finishes running. There’s even a skill that will pop open a Command Center walkthrough from the environment of your choice. Or you can just keep Command Center running while you do your work elsewhere, and if your AI deletes anything, you have Command Center’s snapshots to the rescue.<p>We launched quietly last year and have been refining since. The quality and usability have kept going up, and Command Center is now ready for a lot more attention.<p>Since our quiet launch, we’ve seen at least a dozen other agentic coding environments appear….approximately all of which have the same feature set focused on the part which is already easy (generating the first version of the code) and with at best a shoddy answer to the hard part (everything that comes after). Command Center’s focus is making the hard parts easy.<p>Here’s what our users have to say:<p>“[The refactorings] give your LLM taste. I’ve never seen an LLM write code this good before.” — Doug Slater, Staff Engineer, Climavision<p>“With Command Center walkthroughs, I can get through a 400-line diff in less than half the time.” — Prateek Kumar, Platfor Engineer, Sumo Logic<p>This product is not for everyone. If you’re someone who preaches “the prompt is the source, the code is the compiler output,” then you probably won’t enjoy Command Center.<p>But if you want to uphold traditional engineering discipline while also shipping 20 PRs a day, then this is the environment for you.

FrontierCode

Show HN: macOS Apps on Linux: SwiftUI for Linux (and AppKit, NSFoundation, etc.) I made an open-source project that will take an existing macOS swift project and make it easily compile into a Linux (GTK&#x2F; or Qt). It&#x27;s part of a new quality Swift-first OS I am making called QuillOS.<p>I&#x27;m eager for help and for feedback.<p>Also looking for people who have Swift code (there is very little open source swift code) who can give me example apps to compile against this to find any missing holes. The simpler&#x2F;smaller the better but any size good.<p>It&#x27;s also easy to convert any working iOS app and adapt it to macOS with Claude, and then also cross-compile to Linux with this.<p><a href="https:&#x2F;&#x2F;github.com&#x2F;Lore-Hex&#x2F;QuillUI" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;Lore-Hex&#x2F;QuillUI</a>

Show HN: HTTP/3 and raw QUIC client/server APIs for Node.js I built this because I wanted to make outbound and accept inbound HTTP&#x2F;3 and raw QUIC connections from ordinary Node.js code, without building Node from source or putting everything behind a reverse proxy.<p>Repo: <a href="https:&#x2F;&#x2F;github.com&#x2F;currentspace&#x2F;http3" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;currentspace&#x2F;http3</a> npm: <a href="https:&#x2F;&#x2F;www.npmjs.com&#x2F;package&#x2F;@currentspace&#x2F;http3" rel="nofollow">https:&#x2F;&#x2F;www.npmjs.com&#x2F;package&#x2F;@currentspace&#x2F;http3</a><p>It’s a native package around Rust&#x2F;quiche. It supports both client and server APIs, I&#x27;m using it in a couple of projects: creating raw QUIC streams, datagrams, custom ALPN, session behavior, and HTTP&#x2F;3 client work from Node.<p>I&#x27;ve tried to be very safe in the native code, written in rust, with proofs around the parts I was most concerned about getting wrong. I have it hosting a couple of sites as HTTP3 endpoints and found it working well.

Show HN: AI Pair Programmer for Emacs I built a pair programmer, using AI, but now am trying to go slow with new languages and paradigms using this package.<p>I have noticed a decline in my programming skills, and wondered why I couldn&#x27;t use AI as a pair programmer. Why can it watch what I&#x27;m doing over my shoulder and suggest changes? That way I can struggle through problems still and actually learn something.<p>Results have been good so far :)

The Economics of Speculative Decoding

Show HN: A minimal, ad-free World Cup web-app for fixtures and live scores Hi all! With the World Cup around the corner, and being a football fan, I went looking for apps that would give me a detailed overview of groups, matches categorized by group or team, a daily timeline of when games happen that day (especially useful for us in Europe, since some games run pretty late), and a way to follow my favorite team or teams. The problem I ran into was that most apps out there are pretty bloated — like, really bloated. The ones that weren&#x27;t either didn&#x27;t focus on the World Cup specifically, or were ridden with betting ads and ads in general. So I built a very minimal ad-free (mostly tailored for myself) World Cup web app for fixtures and live scores. The fixture data comes from the openfootball&#x2F;worldcup.json project - <a href="https:&#x2F;&#x2F;github.com&#x2F;openfootball&#x2F;worldcup.json" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;openfootball&#x2F;worldcup.json</a>. I hope you find it helpful, would love any feedback.

Show HN: Gitdot – a better GitHub. Open-source, anti-AI, and written in Rust What works now: user signups, org creations, private&#x2F;public repos, and importing GitHub repositories (both as read-only mirrors and full migrations). So basically, you can create, push and pull to a repo, but we don&#x27;t have many features quite yet (issues, PRs, CI).<p>What is a bit unique is: 1) we built it in Rust and 2) the website is a little odd. Its design is inspired by CLIs (e.g., fzf, broot, vim) instead of web apps, and as such, lacks some affordances that you might typically expect in favor of keyboard-driven instant navigations (we have the very ambitious goal of an FCP of 100ms). In case you&#x27;re curious, here&#x27;s how we we built it: <a href="https:&#x2F;&#x2F;gitdot.io&#x2F;designs">https:&#x2F;&#x2F;gitdot.io&#x2F;designs</a><p>We recognize that we&#x27;re making some bold claims here and are also well aware that we have much to learn. Building software is still hard, and that&#x27;s a fact we seem to relearn everyday.<p>But we wanted to share what we built so far nonetheless.<p>Cheers, thank y&#x27;all for reading, and till the next —paul &amp; mikkel.

Ear Training Practice Exercises

Show HN: Startup sci-fi novel that took me 5 years to write It started after reading Stephen King&#x27;s &quot;On Writing&quot; where he likened the art of writing as the unearthing of an archeological site after you stumbled upon a unique bone of a story. His advice was to choose a domain you are deeply intimate with. For me, I&#x27;ve been a struggling startup founder for 15 years—enough material to inspire a novel.<p>A 1,000-word writing exercise turned into a complete 125k-word manuscript over the course of a year.<p>In year 1, I learned the sheer joy of unencumbered creative flow and authentic expression. A similar flow I used to get from coding (and more recently vibe coding). What made it effortless was a mindset that I was writing for the sake of it, not with the intention of publishing.<p>After a year of keeping it close to my chest, I decided to show it to a few close friends. They liked some of it, destroyed some of it. Some ultimately encouraged me to publish it.<p>In year 2, I learned about the chasm between writing for myself and writing for an audience. Nerdy stuff I thought were clever completely flew over my readers&#x27; heads. So I studied a dozen textbooks on literature, prose, poetry, voice, grammar, and completely rewrote the manuscript twice over, this time with the audience in mind. There is a lot more finesse to writing than I originally appreciated.<p>In year 3, I felt ready to pitch literary agents. The reason wasn&#x27;t to make a career out of writing, but to learn from professionals. After 100 personalized pitches and 0 offers of representation, I learned that pitching agents was much harder than pitching VCs. Especially for a niche novel like mine; fellow startup founders was too small of a TAM.<p>In year 4, I engaged with a professional author&#x2F;editor (Rob Hart, author of The Warehouse), who gave me essays worth of incredible developmental feedback. Lots of nuanced feedback I couldn&#x27;t get from textbooks. Per his advice, I started back at chapter 1 and refactored the whole manuscript. I distilled it down to the best 88k words.<p>The tinkering never stops; when do you know it&#x27;s done? I realized that I kept on tinkering because it was more comfortable than overcoming the fear of launching. Today, on 06&#x2F;08&#x2F;26, almost 5 years after that Stephen King writing exercise, I&#x27;m ready to say “ship it.”<p>Blockchained is a near-future startup sci-fi thriller that chronicles a struggling startup founder who meets a mysterious investor in Hong Kong. Little does he know that the too-good-to-be-true investor works for the Chinese government.<p>Blockchained was written for the fellow startup founders, engineers, and near-future sci-fi enthusiasts. In other words, HN community, you are my target audience<p>Sample chapters available at <a href="https:&#x2F;&#x2F;www.blockchainednovel.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.blockchainednovel.com&#x2F;</a> — eBook and paperback available today. Hardcover edition coming soon.<p>I suppose we live in an era where it must be qualified that Blockchained was 99.9% lovingly handcrafted. No AI was used to write this novel aside from research, spellcheck, grammar, and the occasional phrasing checks.

Show HN: Quick games disguised as boring spreadsheets I posted a version of this over a year ago but decided to rebuild it recently.<p>Bored Spreadsheet is a collection of quick and easy games that look like a spreadsheet from a distance. I have tightened the app to be a collection of 6 games: Minesweeper, 2048, solitaire, sudoku, a market trading game and a daily reconciliation puzzle where the player must find bad data in a fake table.<p>The games are free to play but sign up is required to submit your scores to the leaderboard. As was the original intention over a year ago, I hope this proves useful to those office workers who have a lot of downtime in between tasks or meetings yet don’t have the freedom to open Youtube or Cyberpunk 2077 on their work computers. Ironically my work network has blocked the website as it “contains non-business-related services” – I hope you have better luck than me!
